Hi again Siang,

In general, it will be easier to use a high level language, for reasons that are probably intuitive to you. You said that you are familiar with the Taylor series, but you don't know how to write them into a program. With assembler it will be extremely cryptic, moving terms into various registers, popping and pushing things onto the stack, and then accumulating them together. But with C or BASIC it is simply a matter of writing the equation to as many terms as your desired precision requires. Let the compiler take care of stacks and registers.

As to how much memory it will require, you will have to rely on your compiler to determine this. Or, just compile it and see.

Keep us posted on how it goes. We won't do the work for you, but we will gladly help.
